"I knew it was going to be hard, but I don't think that there's anything anybody can say that can really, really prepare you for what [Juan Pablo's] about to experience," she said. "It's unlike anything that anybody's ever gone through."

However, Maynard described the show as a "blessing" and offered some tips to Galavis, who was unveiled as the new Bachelor earlier this week.

"Drink lots of coffee, because you're not going to get much sleep," she said. "And ask lots of questions and based on their answers, follow your gut."

Maynard, who has a young daughter called Ricki, also advised Galavis to think of his 4-year-old daughter Camila during his time on The Bachelor.

"It's a really hard situation to be in anyway, being the Bachelor or Bachelorette, but being a single parent into the mix makes it that much harder," she said. "But it's also a blessing, because children are brutally honest and keep you very grounded. So I just say keep talking to her every day and keep her at the forefront of your mind in all your choices, and I'm sure he will."
